Weekly Review Summary: AI stocks traded erratically like memecoins this week, while Bitcoin remained relatively flat around $64,000. Major market volatility stemmed from a forced liquidation by the "Situational Awareness" fund, contributing to a sharp sell-off in chip and AI stocks, particularly impacting Asian markets like South Korea's KOSPI. The Fed's signals and broader macro concerns added to the uncertainty. In crypto, the news was largely overshadowed by traditional finance but remained negative. Several crypto firms announced closures (BitMart) or bankruptcies (Storj Labs), and layoffs continued across the industry (Coinbase, Uphold). MicroStrategy notably shifted its strategy, using proceeds to buy back its own stock instead of purchasing more Bitcoin, drawing criticism. DeFi saw success stories like Trade.xyz on Hyperliquid, but also potential risks from insider trading and questions about platform dependence (e.g., Pump.fun on Solana). The intersection of AI and crypto gained attention with renewed hype around projects like Bittensor ($TAO). A critical security warning was reiterated for Coldcard wallet users regarding a potential private key vulnerability, emphasizing the high responsibility of self-custody. The overall tone cautioned against panic but urged preparedness amid a challenging market.

MicroStrategy's Executive Chairman Michael Saylor has fueled speculation about a new Bitcoin purchase by posting "Bitcoin Drive engaged" on August 2, accompanied by the company's customary purchase tracker. This aligns with his pattern of hinting at treasury changes ahead of weekly reports. The accompanying report showed MicroStrategy's Bitcoin holdings at 843,775 BTC, with an average cost of $75,653 per coin and an unrealized loss of -$10.58B. A similar signal preceded the company's July 27 announcement, strengthening expectations for a treasury update on Monday. However, MicroStrategy's real-time ledger reflects two recent Bitcoin sales totaling 3,588 BTC, reducing holdings from 847,363 BTC to the current 843,775 BTC. The company stated these sales funded preferred stock dividends and replenished its U.S. dollar reserve. Recent reports indicate the company made no Bitcoin purchases the week ending July 26 while increasing its dollar reserve to approximately $3.75B. The company faces financial headwinds after reporting an $8.33B operating loss for Q2 2026, including an $8.32B unrealized loss on its digital assets. Management may sell up to $1.25B more in Bitcoin to meet cash obligations. The expected Monday update will reveal if the "Bitcoin Drive" signal marks a return to accumulation as MicroStrategy balances its massive Bitcoin stash against growing cash commitments.

Bitcoin miners are capitulating as evidenced by a sustained drop in network hash rate and a record-steep 19.9% decline in mining difficulty, signaling the shuttering of unprofitable machines. However, in a significant divergence from historical patterns, the stocks of publicly traded mining companies have soared, with one major player gaining over 430% in the past year, even as BTC's price fell roughly 46%. This surge is largely attributed to these companies pivoting toward the more lucrative AI narrative. Simultaneously, miners face a structural squeeze. Daily block reward revenue in BTC terms has hit a new all-time low following the latest halving, with current dollar-denominated daily revenue around $30 million compared to a longer-term average of ~$40 million. Fee revenue remains negligible, covering less than one block's subsidy over a 28-day average and accounting for only about ten minutes of the network's daily security budget. This capitulation cycle is unique: miner stress and crypto price weakness have decoupled due to alternative revenue streams (AI), while the long-term reliance on increasing bitcoin prices to offset shrinking subsidies continues, with fee income still far from filling the impending gap.

Coldcard hardware wallet users are facing a new wave of coordinated attacks targeting a firmware flaw, with researcher Alex Thorn flagging 218 recent transactions moving approximately 389 Bitcoin from potentially impacted addresses. The attack pattern shows a high rate of transactions targeting unique victim addresses, differing from previous waves. The vulnerability, which causes affected devices to generate weaker wallet seeds, is estimated to have impacted over 1,100 wallets, leading to around $90 million in Bitcoin stolen. Thorn advises affected users who control their keys may attempt to move funds with a higher-fee transaction before the attacker's transactions are confirmed.

**Forbes: Quantum Computing Threatens 7 Million Bitcoin — Must BTC Change Its "Lock"?** A Forbes article explores the emerging threat quantum computing poses to Bitcoin's cryptography, which secures an estimated 7 million BTC (~$470 billion). While a machine capable of breaking Bitcoin's Elliptic Curve Digital Signature Algorithm (ECDSA) doesn't yet exist, researchers are raising alarms. Google studies suggest the required number of qubits for such an attack is decreasing rapidly. The risk applies to "exposed" public keys, found in early "Satoshi-era" addresses or reused addresses, but exposure does not equal theft. The Bitcoin developer community is divided on solutions. Proposals include BIP-360 for new quantum-resistant address types and the more controversial BIP-361, which would eventually freeze non-migrated, vulnerable coins to prevent future quantum theft. Startups like American Fortress are entering the space, claiming solutions like a backward-compatible soft fork to auto-freeze vulnerable wallets. However, its claims are met with caution as its technical paper is unpublished and its design unaudited. The article frames this as a high-stakes race, weighing urgent security upgrades against Bitcoin's foundational principles and long-term viability.
